CHARLES E. STANLEY, OF CANTON, OHIO.

TROLLEY-G UARD.

SPECIFICATION forming part of Letters Patent No. 680,286, dated August 13, 1901.

Application filed March 20, 1901. Serial No. 52,027. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. STANLEY, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio,

, have invented new and useful Improvements in Trolley-Guards, of which the following is a specification.

My invention relates to improvements in trolley-guards and it consists of a yoke journaled to the fork of a trolley-arm, the upper free ends of which yoke have journaled thereto beveled wheels adapted to engage the trolley-wire'and prevent its passing off from the trolley-wheel.

In, the accompanying drawings similar letters of reference refer to similar parts.

Figure 1 is a front view. Fig. 2 is a side view. Fig. 3 is a top view. Fig.4 is a perspective view of the beveled guard-wheels. Fig. 5 is a perspective view of the yoke. Fig. 6 is a rear view of one of the'guard-wheels.

The trolley-arm A is of the usual wellknown form, terminating in the fork B, provided with two limbs or members 12 I), having journaled therein the trolley-Wheel O. The yoke D consists of a substantially U- shaped metallic frame journaled in the trolley-fork upon the shaft 6 upon which the trolley-wheel O is journaled. The free ends of the yoke extend up above the line of the top of the trolley-wheel and have journaled in their ends the beveled-edge guard-wheels (Z and d, which revolve upon the pins or shafts d and d In operation the trolley-wire E passes down between the guard-wheels d d until it rests upon the trolley-wheel G. If for any reason the vibration of the wire or other causes the trolley-wire has a tendency to rise and disengage itself from the trolley-wheel, one of the guard-wheels d d engages the same and immediately begins to revolve, and the tendency is to push the wire down into position.

It will be observed that this device, which fork of a trolley-arm and to have journaled in the free ends of the yoke beveled-edge gear-wheels.

Having thus fully described my invention, what I desire to secure and claim by Letters Patent is 1. In a trolley-guard, the combination with the trolley-arm provided with a fork, a shaft mounted in the arms of the fork, and a trolley-wheel journaled upon said shaft, of a guard consisting of an elongated, counterbalanced U-shaped yoke journaled upon the said trolley-wheel shaft between the arms of the fork, and beveled-edge guide-wheels journaled upon horizontal shafts mounted in the free ends of the arms of the yoke and spaced apart and arranged vertically above the sides of the trolley-wheel with their beveled edges extending inwardly and above the flaring sides of said Wheel, substantially as described.

2. A trolley-guard consisting of a metallic yoke adapted to be journaled in the forks of a trolley-arm, shafts mounted horizontally in the free ends of the yoke, and spaced, vertically-arranged guide-wheels journaled upon said shafts and having inwardly-extending beveled edges, substantially as described.

In testimony whereof I. have hereunto set my hand in the presence of two subscribing witnesses.

CHARLES E. STANLEY.
